Do We Have To Apply a Moisturizer After a Serum?

Serums are highly concentrated treatments containing active molecules such as salicylic acid, retinol or hyaluronic acid. They allow to correct certain targeted skin problems such as imperfections, signs of aging or dehydration.

However, in order to reinforce the skin barrier with the stratum corneum and to protect the skin from external aggressions, it is important to apply ingredients that form a protective film on the entire surface of the epidermis, preventing water from evaporating and preventing the entry of foreign substances. These ingredients include film-forming agents, occlusives, humectants or fats. In fact, they will restore the hydrolipidic film of the epidermis and thus seal in moisture by maintaining the skin's water content.

So, after applying your serum, remember to always protect your skin from dehydration, morning and night, by applying a moisturizing cream, a night serum or a plant oil.
